I've drag a grid control and make a SqlDataSource for it. I can fill data for first column, it's easy because it's text and all I need is enter Field Name. But for second column, it's repositoryItemSearchLookUpEdit and I can't do this. Each row of this control is not same value, example:
--- row 1 column 2 (a, b, c)
--- row 2 column 2 (d, e, f)
How can I do that?

P/S: I use windows form with C# and DevExpress 15.1. Thank you so much!
